Distribution. — Stations A32-39, At502, At526 and At529. These

Holoporella magnifica Osburn, 1914 



Osburn 1914:216 and 1940:455. Canu and Bassler 1928: 144. 



A large, coarse species, which encrusts shells, sponges, etc. Osburn 

 described it from the Tortugas Islands at 19 fathoms and listed it also 

 from Biscayne Key, Florida, Porto Rico, the Bermuda Islands and Beau- 

 fort, North Carolina; Canu and Bassler recorded it for the Gulf of 

 Mexico and east of Yucatan. 



Distribution. — Station At505, Aruba Island at 23 fms, one small 

 colony. 



Holoporella vagans (Busk), 1855 



Canu and Bassler 1928: 148. Osburn 1940: 456. 



This appears to be the only species in the West Indian region which 

 bears a notch (not a sinus) in the proximal border of the aperture. Canu 

 and Bassler recorded it from the Straits of Florida and off Miami, 

 Florida, down to 56 fathoms. Osburn listed it for Porto Rico and the 

 Bermuda Islands. It may not be the vagans of Busk as it differs in several 

 minor characters, but I have followed Canu and Bassler until the oppor- 

 tunity arrives to compare with Busk's tj^pe material. 



Distribution. — Stations A14-39, A42-39 and At526. These stations 

 place the locations at Cape la Vela, Colombia; Margarita and Tortuga 

 Islands at 21 to 41 fms. 



Holoporella subalba Canu and Bassler, 1928 



Canu and Bassler 1928: 146. Osburn 1940:456. 



The species was described from east of Yucatan, down to 25 fathoms. 

 Osburn has recorded it from Porto Rico and off Havana, Cuba. It forms 

 rather large encrustations, ivory or dead white in color, with large, long- 

 spatulate avicularia.
